1.1本文件涵盖了使用两种替代强制选择确定两种产品之间偏好的程序，其中可能包括也可能不包括不选择偏好的选项。 1.2配对偏好测试确定给定受访者群体在两种产品之间是否存在统计上显著的偏好。必须仔细考虑目标人群。 1.3该方法在单个评估环境中建立偏好。重复测试不在本文件范围内。 1.4配对偏好测试可以解决整体偏好或对特定感官属性的偏好。 1.5该方法不能直接确定偏好的大小。 1.6本方法不涉及两个样本是否被视为不同。见试验方法E 2164。 1.7配对偏好测试对受访者来说是一项简单的任务，可以用于阅读或理解技能最低的人群，或者两者都有。 1.8偏好不是产品的固有属性，例如色调，而是与受访者的情感或享乐反应相关的主观衡量标准。它不同于测量产品客观特征的配对比较测试。偏好结果始终取决于抽样人群。 1.9本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This document covers a procedure for determining preference between two products using a two-alternative forced-choice, which may or may not include the option of choosing no preference. 1.2 A paired preference test determines whether there is a statistically significant preference between two products for a given population of respondents. The target population must be carefully considered. 1.3 This method establishes preference in a single evaluation context. Replicated tests will not be covered within the scope of this document. 1.4 Paired preference testing can address overall preference or preference for a specified sensory attribute. 1.5 The method does not directly determine the magnitude of preference. 1.6 This method does not address whether or not two samples are perceived as different. See Test Method E 2164. 1.7 A paired preference test is a simple task for respondents, and can be used with populations that have minimal reading or comprehension skills, or both. 1.8 Preference is not an intrinsic attribute of the product, such as hue is, but is a subjective measure relating to respondents' affective or hedonic response. It differs from paired comparison testing which measures objective characteristics of the product. Preference results are always dependent on the population sampled. 1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
